jquery Ajax는 Select를 구현하여 데이터 인스턴스 구문 분석을 동적으로 추가합니다.

<li class="form-row">
<span style="white-space:pre"> </span>
<span class="form-lbl"><i class="tip form-tip">*</i>车系</span>
 <select class="form-select" name="modelId">
 </select>
</li>

function getModelList(){ 
 var brandId = $("select[name=brandId]").val(); 
 $("select[name=modelId]").empty(); //清空
 $.ajax({url:'/getModelList.do',
 type:"post",
 data:{
 brandId : brandId
 },
 cache: false,
 error:function(){
 }, 
 success:function(data){
 var modelList = data.modelList;
 if(modelList && modelList.length != 0){
 for(var i=0; i<modelList.length; i++){
  var option="<option value=\""+modelList[i].modelId+"\"";
  if(_LastModelId && _LastModelId==modelList[i].modelId){
  option += " selected=\"selected\" "; //默认选中
  _LastModelId=null;
  }
  option += ">"+modelList[i].modelName+"</option>"; //动态添加数据
  $("select[name=modelId]").append(option);
 }
 }
 }
 });
}
